摘要

Phalaenopsis?is the most important potted orchid genus in the world. However, the low seedling survival rate, long vegetative growth period and disease outbreak are problems in production. Orchid micorrhizal fungi (OMF) are their obligate partners in orchid physiology. Orchids use their symbionts to gain access to organic and mineral nutrients by increasing nutrient absorption and translocation to plants under natural conditions. The benefit of orchid mycorrhizal symbiosis using?Phalaenopsisas model plants was conducted. We inoculated?in vitro grown plantlets ofDoritaenopsis?Taisuco Wonder ‘King Car Butterfly KC1111’ and?Phalaenopsis?Tai Lin Redangel ‘V31‘ with two OMF isolates,?Ceratobasidium?sp. AG-A (R02) andRizoctonia solani?AG-6 (R04). The effects of OMFs on orchid plant growth andErwinia?soft rot progression were examined after two months of?ex vitro?growth. The results showed that the presence of OMFs in?Phalaenopsis?roots significantly increased the growth and soft rot resistance of plants. Selectivity of cultivar type to different OMF was also observed. The relevance of this findings and future work are discussed.
